Like a three-story inn for beneficial insects, this attractive insect house provides just the right habitat for some of gardeners' best friends. Solitary bees will nest in the bamboo "upstairs" and the holes in the first floor wood block, so they'll be ready to pollinate your garden come spring. The middle floor will attract pest-eating lacewings and ladybugs; the door opens so you can add a bit of dried grass and a few twigs for them to settle on. We designed the house to the exacting specifications of the insects so they'll feel right at home.
